I'm using Vegas 19, which recently informed me about new upgrade available on-line. The upgrade downloaded without problems and was installed also without problems. When Vegas 19 was restarted it displayed registration dialog and after clicking on Activate and register button gives this "An online connection could not be established. Please make sure your computer is correctly connected to the Internet. A fire wall may also be blocking access" - well I'm pretty sure my computer is connected to the Internet, otherwise how the Vegas 19 would learn about upgrade? I've tried suggested option of resetting Internet options, but this didn't help.
I'm running Windows 11. I'm getting email messages from Vegas team about shiny new version 20, but for sure I'm not going to upgrade to this marvel of software engineering since I don't have Internet connection.
